| 2000 | Invention patented by Staffan Soderberg and Peter Littecke on May 17th, 2000. Abstract: The present invention describes a coated CBN cutting tool for metal machining. The tool is composed of one or more CBN bodies with or without a cemented carbide backing. The coating comprises one or more layers of refractory compounds of which at least one layer consists of fine-grained, crystalline .gamma.-phase alumina, Al.sub.2 O.sub.3, with a grain give less than 0.1 .mu.m. The .gamma.-phase alumina is deposited with a Plasma Activated Chemical Vapor Deposition (PACVD) process in which the plasma is produced by applying a bipolar pulsed DC voltage across two electrodes to which the tool substrates to be coated are fixtured and electrically connected. |
